Types

type Lexer

type Lexer interface {
	SetTypeSystemInput(input []byte) error
	SetExecutableInput(input []byte) error
	Read() (tok token.Token)
	Peek(ignoreWhitespace bool) keyword.Keyword
	ByteSlice(reference document.ByteSliceReference) document.ByteSlice
	TextPosition() position.Position
}

Lexer is the interface used by the Parser to lex tokens

type Option

type Option func(options *Options)

func WithMinimumSliceSize

func WithMinimumSliceSize(size int) Option

func WithPoolSize

func WithPoolSize(poolSize int) Option

type Options

type Options struct {
	// contains filtered or unexported fields
}

}

ParsedDefinitions contains all parsed definitions to avoid deeply nested data structures while parsing

type Parser

type Parser struct {
	ParsedDefinitions ParsedDefinitions
	// contains filtered or unexported fields
}

Parser holds the lexer and a buffer for writing literals

func NewParser

func NewParser(withOptions ...Option) *Parser

NewParser returns a new parser using a buffered runestringer

func (*Parser) ByteSlice

func (p *Parser) ByteSlice(reference document.ByteSliceReference) document.ByteSlice

func (*Parser) CachedByteSlice

func (p *Parser) CachedByteSlice(i int) document.ByteSlice

func (*Parser) InitDirectiveSet

func (p *Parser) InitDirectiveSet(set *document.DirectiveSet)

func (*Parser) ParseExecutableDefinition

func (p *Parser) ParseExecutableDefinition(input []byte) (err error)

ParseExecutableDefinition parses an ExecutableDefinition from an io.Reader

func (*Parser) ParseTypeSystemDefinition

func (p *Parser) ParseTypeSystemDefinition(input []byte) (err error)

ParseTypeSystemDefinition parses a TypeSystemDefinition from an io.Reader

func (*Parser) TextPosition

func (p *Parser) TextPosition() position.Position
